Vampire Deer are actually a Real animal. A type of Musk deer that has evolved Tusks but they look like miniature Fangs to Us.

When I first saw this I thought it had to be photoshopped but no these are indeed real creatures. While they look like they might be actual vampires they do not use the fangs for any hunting they are like tusks or antlers and I believe can help them to attract mates. It is strange to have evolved these but they are actually pretty cute I think.
